On NASA’s first try, on 29 August, lightning near the launch pad delayed work to fill the rocket’s fuel tanks. Then two hydrogen leaks appeared. Finally, a sensor indicated that one of the SLS’s four main engines was not chilled to the temperature necessary to receive fuel before lift-off. NASA halted the launch attempt — although it later found th...
As a rocket propellant, liquid hydrogen is lightweight and powerful. When combined with liquid oxygen, it produces the highest specific impulse — a measure of the thrust it can generate — of any rocket fuel. So NASA has continued using it even though it can be extremely finicky and prone to leaks. “Hydrogen is a challenging molecule, but it’s worth...
For the moment, engineers are working to fix the hydrogen leaks while the SLS is still on the launch pad at the Kennedy Space Center in Florida. But there are many constantly changing factors that dictate when and how NASA might next try to launch. For instance, the rocket contains a safety system that is designed to destroy it if it veers off cour...
The experiments — including ten small satellites, plus modules meant to test biological and radiation hazards in deep space — are in limbo as NASA assesses a new flight schedule. Five of the satellites have not had their batteries charged since being installed on the rocket, in some cases more than a year ago. NASA would have to disassemble parts o...
Not significantly, unless the rocket remains grounded for many months. Launch dates for space flight slip regularly, although the Artemis I delays are particularly grating because the SLS has been in development for more than a decade and has run significantly behind schedule and over budget. After the recent launch cancellations, NASA administrato...

Jan 9, 2024 · NASA announced today (Jan. 9) that its flagship Artemis 2 moon mission will be delayed until September 2025 due to technical challenges and safety concerns.
Jan 9, 2024 · The news came barely an hour after a Pittsburgh company abandoned its own attempt to land its spacecraft on the moon because of a mission-ending fuel leak. Launched Monday as part of NASA’s commercial lunar program, Astrobotic Technology’s Peregrine lander was supposed to serve as a scout for the astronauts.
Jan 9, 2024 · Nasa says the delay to what's known as its Artemis III mission will enable further technology development. Fundamentally, the agency still doesn't have a craft to put astronauts on the Moon...
